Total Commander

Currently it's impossible to unselect files/folders by clicking blank space. You should click other file or folder item to unselect something unlike explorer operation.

I think it's somehow inconvenient but I'm not sure if it is an intentional action. What do you think of it? Can it be possible to allow unselection by clicking black space?

The problem might be that in general there is no blank space. Of course there is space when there is short filelist but this is nothing you can rely on.
The problem is - as mentioned in another thread - that there is no space left and right of the columns.

Press spacebar instead of clicking blank space?

Hmm, it make senses though I'm under UHD desktop with 100% dpi.

What about unselection by wheel click?
